Python RegEx Compile – re.compile()

# Module Regular Expression is imported
import re

# compile() creates regular expression character class [a-d], which is equivalent to [abcd].
# class [abcd] will match with string with 'a', 'b', 'c', 'd'.
p = re.compile('[a-e]')

# findall() searches for the Regular Expression nd return a list upon finding
print(p.findall("Hello, Welcome to Softhunt.net Tutorial Website"))

Python RegEx re.compile()

import re

# w is equivalent to [a-zA-Z0-9_].
p = re.compile('w')
print(p.findall("He said * in some_lang."))

# w+ matches to group of alphanumeric character.
p = re.compile('w+')
print(p.findall("I went to him at 9 A.M., he 
said *** in some_language."))

# W matches to non alphanumeric characters.
p = re.compile('W')
print(p.findall("he said *** in some_language."))
